Xa abenzi bezacholo befuna a ulahlekile umzi-mveliso wekhithi yokuphosa, abakhangeli nje izixhobo-bafuna ukuthembeka phantsi kobushushu, ukuchaneka kulawulo lokunciphisa, kunye nokuphindaphinda kwimijikelo yotyalo-mali eninzi. Siye sabona abaqulunqi beodola iikhithi kwi-intanethi kuphela ukujongana neeflaski ezijijekileyo, ukuhamba kwesinyithi okungahambelaniyo, okanye ukusilela kweqokobhe leceramic emva kokugalelwa kwe-10 yokuqala. Yiyo loo nto iingcali zisiya zigqitha kubaboneleli bamayeza enziwe afana nalawo enziwe ngabenzi-kwaye baye ngqo kubavelisi abanomgangatho wokuphonononga wodidi lwemizi-mveliso.
Kutheni i-Industrial Casting Rigor iguqulela kwiMpumelelo yobucwebe
Ukuphoswa kwewax elahlekileyo yobucwebe obuhle kufuna unyamezelo oluqinileyo-kaninzi ± 0.05 mm kumanqindi eringi okanye izihlalo ze-bezel-kodwa uninzi lwezixhobo zokuzilibazisa zicinga ukuba uya kubhamba, ufake ifayile, kwaye usebenze kwakhona ngesandla. Akunjalo kwiifektri ezakhelwe imizimba yevalvu ye-hydraulic kunye nezindlu zempompo ye-cobalt-alloy. Apho, yonke iflaski ibhakwe kwangaphambili ngokwemilinganiselo yerempu elawulwayo. Yonke ibhetshi ye-slurry idlula i-viscosity kunye nokugawulwa kwe-pH. Wonke umjikelo wedewax ulandela iiprofayili zexesha lobushushu eziqinisekisiweyo ngokuchasene ne-AMS 5387 yokuziphatha kwe-alloy-hayi nje "into esebenzela isilivere."
Sivavanye izinto ezintathu eziqhelekileyo ezilahlekileyo zekhithi ye-wax-i-sprue formers, i-powders yotyalo-mali, kunye ne-vacuum flasks-ngokuchasene ne-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Umahluko wawungekho ubuqili: utyalo-mali lwabo olusekelwe kwi-silica lubonise i-42% ngaphantsi kwe-thermal yokwandisa i-drift emva kwe-600 ° C ukubamba; imithi yabo ye-sprue yensimbi engenasici igcine ukuthe tye phantsi kwe-1200 psi centrifugal force; amagumbi abo e-vacuum abambe i-99.2% yokunciphisa i-atmospheric kwimizuzu ye-8 +-ibaluleke kakhulu ekupheliseni i-micro-porosity kwi-18K yegolide.
Oku asikobunjineli obugqithisileyo. Kubuchule bokuthwala: inkqubo efanayo yolawulo ethintela ukuqhekeka kwi-T800 cobalt-alloy nozzles phantsi koxinzelelo lwe-oyile ye-300-bar ikwayekisa ifiligree entle ekunyamalale phakathi kokugalela.
Eyona nto ibalulekileyo kwiKhithi eLungele iMveliso
Ulibale amabango okuthengisa "zonke-in-one". Ukusebenza kwehlabathi lokwenyani kuxhomekeke kwizinto ezine ezingaxoxiswana:
- Ukulandeleka kwezinto: Iipowders zotyalo-mali eziqinisekisiweyo-zingaphinda zipakishwe i-surplus-kunye nenqanaba elipheleleyo le-CoA (iSatifikethi sokuHlalutya) se-SiO₂ ubunyulu, umxholo womlotha we-binder, kunye nokusabalalisa ubungakanani bamasuntswana (D₅₀ ≤ 28 µm)
- Uzinzo lweDimensional: Iiflasks ezenziwe ngoomatshini ukusuka kwi-316L yoxinzelelo-i-stainless-engaphoswanga i-aluminium-kunye ne-CMM eqinisekisiweyo yokunyamezela udonga lwe-± 0.15 mm
- Ulungelelwaniso lweprotocol yokutshisa: Iikhithi ezilungiselelwe indlela ethile / iprofayile yokumanzisa ehambelana nempendulo ye-thermocouple yesithando somlilo-hayi igeneric "landela imiyalelo"
- Ukuxhathisa ukothuka kwe-thermal: Iigobolondo zeCeramic zifanelekile ukuba ziphile ukucima ngokukhawuleza ukusuka kwi-950 ° C ngaphandle kwe-spalling-iqinisekisiwe ngovavanyo lwe-ASTM C1161
Uninzi lweekhithi eziphuma kwishelufu aziphumeleli kwi-#1 kunye ne-#3. Bathumela umgubo ngaphandle kwe-ID yebhetshi. Bancoma iigophe ezidityanisiweyo ezingayihoyiyo i-15-minute thermal lag yesithando somlilo sakho. Ufumanisa oku kuphela emva kokulahlekelwa iiyure ze-12 kunye ne-$ 200 kwiimodeli ze-wax.
Indlela Udibaniso oluthe nkqo oluSombulula ngamanqaku eentlungu zokwenyani
Abanye baphikisa ngelithi: “Ukwenziwa kwezacholo akufuni lawulo lwe-aerospace.” Kodwa qwalasela oku-xa umthengi esithumelela imodeli ye-wax eprintiweyo ye-3D yebhendi yomtshato we-titanium, iinjineli zethu azithululi nje. Baqhuba uhlalutyo lwe-GD & T kwi-STL, ukulinganisa ukuhamba kwesinyithi kwi-MAGMASOFT®, ukulungelelanisa ijometri ye-sprue ukukhusela i-turbulence kwimigudu emxinwa, emva koko umatshini wokubumba i-mold cavity kwi-5-axis CNC-konke phantsi kophahla olulodwa. Eso siseko sinye sixhasa abavelisi bezacholo abancinci abadinga:
- Ubungakanani beflask eyenzelwe wena (hayi nje 2" × 3 ″ isitokhwe)
- Imixube yotyalo-mali engekho mgangathweni (umzekelo, i-zircon-silica hybrids yeplatinam yeenkcukacha eziphezulu)
- Ishedyuli yokutshiswa kwangaphambili ebotshelelwe kwiindibaniselwano ezithile zeresin/wax
- Iingxelo ze-Post-cast dimensional ezine-CMM zokwaleka kwescan ebonisa i-shrinkage vectors
Akukho kususwa ngesandla. Akukho kulibaziseka komthengisi. Iqela elinye nje lobugcisa—ukususela kushicilelo lwewax ukuya kutsho ekugqityweni kwemidlalo—lithetha ulwimi olufanayo lwe-metrology.
Ukujonga Phambili: Apho i-Precision Casting ibhekisa khona
Umda olandelayo awukho iziko zikhulu okanye ukutshiswa ngokukhawuleza. Lulawulo lwenkqubo yomxube: ukubethelela i-thermocouples yexesha lokwenyani ngaphakathi kumaqokobhe otyalo-mali, kusetyenziswa i-AI ukunxibelelanisa ufundo lweqokobhe loxinaniso noburhabaxa bokugqibela bomphezulu (Ra), kunye nokudibanisa ijometri ye-CAD ngokuthe ngqo kwiindlela zesixhobo zomthi ze-sprue ezenziwe ngomatshini we-CNC. I-QINGDAO QIANGSENYUAN TECHNOLOGY sele ithumela ezi kuvavanyo lokwenziwa kofakelo lwezonyango-kwaye ezo protokoli ngoku ziyafumaneka kumahlakani ezacholo afuna ukuphinda-phinda okungaphantsi kwe-0.02 mm ukugcinwa kweenkcukacha.
A ulahlekile umzi-mveliso wekhithi yokuphosa ixabiso lakho alithengisi iibhokisi. Ithengisa ukuzithemba okulinganisiweyo. Ithunyelwa ngedatha yokuncipha ebhaliweyo ngealloyi nganye, hayi i-disclaimers. Iyaphendula "Buthini ubukhulu bodonga lobukhulu be-14K rose yegolide kule flaski?" - hayi "Jonga incwadi." Kwaye imi ngasemva kwebhetshi nganye enokulandeleka ngokupheleleyo, ukusuka kwi-silica quarry ukuya ekugqityweni kokusalwa.
Ukuba umsebenzi wakho uxhomekeke kwinto esindayo emlilweni-hayi nje into engena kuwo-awuthengi ikiti. Ukhetha iqabane esele lizisombulule iingxaki ongakhange udibane nazo.
